Iindondo zamehlo, ziyilwe elimangalisayo eliye laguqula ubomi bezigidi zabantu, zinembali etyebileyo nebangel’ umdla eqhubeka kangangeenkulungwane. Ukususela kwisiqalo sabo esiphantsi ukuya kwizinto ezintsha zale mihla, masiqalise uhambo olubanzi ngokuvela kweendondo zamehlo.
Imvelaphi yaMandulo
Iingcambu zeglasi zamehlo zinokulandwa emva kwimpucuko yamandulo. KwiRoma yamandulo, malunga nenkulungwane yokuqala ye-AD, ukusetyenziswa kweglasi yokukhulisa umbono kwabhalwa phantsi. Olu hlobo lokuqala lokukhulisa lwabeka isiseko sokwenziwa kweendondo zamehlo.
Ukuphumelela kwaMaphakathi
Kwakusebudeni bamaxesha aphakathi apho iindondo zamehlo zaqalisa ukumila ngendlela esizazi ngayo namhlanje. Ngenkulungwane ye-13, imonki yase-Italiya egama linguSalvino D'Armate kuthiwa yenza iindondo zokuqala ezinxitywayo. Ezi ndondo zakuqala zaziquka iilensi ezimbini zeconvex ezibanjwe kunye ngefreyimu eyayihlala kwibhulorho yempumlo. Ubukhulu becala zazisetyenziselwa ukulungisa ukubona kude, ukungaboni kakuhle okuqhelekileyo.
Ukuqhubela phambili kweRenaissance
Ixesha le-Renaissance libone inkqubela phambili ebonakalayo kwinkalo ye-optics kunye ne-eyeglass. Ngenkulungwane ye-16, kwaqaliswa iilensi zeconcave ukuze zilungise izinto ezikufutshane. Le mpumelelo ivumele abantu abaneziphene ezahlukeneyo ukuba baxhamle kwiindondo zamehlo.
Ngeli xesha, iiglasi zamehlo nazo zaba yinto yefashoni phakathi kwe-elite. Iifreyimu ezenziwe ngesinyithi esixabisekileyo, njengegolide nesilivere, ezihonjiswe ngobukroti, zaba luphawu lobutyebi newonga.
Uguquko lwezoShishino kunye neMveliso yeMisa
INguquko YezoShishino ngenkulungwane ye-18 yabangela utshintsho olukhulu kwimveliso yeendondo zamehlo. Ngokufika koomatshini kunye nobuchule bokuvelisa ngobuninzi, iindondo zamehlo ziye zafikeleleka ngakumbi kwaye zifikeleleka kubemi abaninzi. Ukuqaliswa kweefreyimu zetsimbi kunye nokukwazi ukwenza iilensi kwiimilo ezahlukeneyo kunye nobukhulu kwandisa ngakumbi ukhetho olukhoyo kubadlali beglasi yamehlo.
Ukunyuka kweOptometry
Ngenkulungwane ye-19, intsimi ye-optometry yavela, igxile kwisayensi yokulungiswa kombono. Oogqirha bamehlo badlale indima ebalulekileyo ekumiseleni nasekufakeni iindondo zamehlo, beqinisekisa ukuba abantu bafumana iilensi ezifanelekileyo ngokweemfuno zabo ezithile ezibonakalayo. Oku kwenziwa ngobungcali bokufakwa kweglasi yamehlo kunye nomyalelo kagqirha kuphawule inyathelo elibalulekileyo ekuphuhliseni iindondo zamehlo.
Izinto ezintsha zale mihla
Inkulungwane yama-20 yeza nezinto ezininzi ezintsha kwiindondo zamehlo. Ekuqaleni kweminyaka yoo-1900, ukungeniswa kwezakhelo zeplastiki kwaliguqula ishishini. Ezi freyimu zikhaphukhaphu kunye nezomeleleyo zithathe indawo yezakhelo zentsimbi zemveli, zinika intuthuzelo enkulu kunye nokhetho lwesitayile.
Embindini wenkulungwane yama-20, uphuhliso lweelensi eziqhubela phambili lubonelele ngenguqu engenamthungo phakathi kwemimandla yombono eyahlukeneyo, ukuphelisa imfuneko yeeperisi ezininzi zeeglasi. Ukongezelela, ukusetyenziswa kwezixhobo ze-lens eziphambili, ezifana ne-polycarbonate kunye neeplastiki eziphezulu zesalathisi, kubangele iilensi ezincinci kunye nekhaphukhaphu, ziphucula zombini induduzo kunye nobuhle.
IiLensi zoQhagamshelwano kunye noTyando lweLaser
Kwisiqingatha sokugqibela senkulungwane yama-20 kuye kwavela ezinye iindlela zokulungisa umbono, njengeecontact lens kunye notyando lwelaser. Iilensi zoqhagamshelwano zinikeze inketho engathintekiyo kwabo banqwenela ukuphepha ukunxiba iindondo zamehlo. Utyando lwamehlo ngeLaser, kwelinye icala, lwabonelela ngesisombululo esisisigxina kwiingxaki zombono ngokulungisa kwakhona i-cornea.
Ngelixa ezi zikhetho ziye zafumana ukuthandwa, iindondo zamehlo zahlala zezona zisetyenziswa kakhulu kwaye zilungele ukulungiswa kombono ngenxa yokusebenziseka kwazo ngokulula, ukufikeleleka, kunye nendalo engaphazamisiyo.
Izinto ezinokwenzeka kwixesha elizayo
Njengoko sijonge kwikamva, ishishini leglasi lamehlo liyaqhubeka nokuvela. Ukuhlanganiswa kweteknoloji kwiiglasi zamehlo kuya kuxhaphaka. Iiglasi ezihlakaniphile, ezixhotyiswe ngezakhono zokwenyani ezandisiweyo, ziyaphuhliswa ukuphucula ubomi bethu bemihla ngemihla, zibonelela ngeempawu ezifana nokuboniswa kolwazi lwexesha lokwenyani kunye nonxibelelwano olungenazandla.
Ukuhambela phambili kwenzululwazi ngezinto eziphathekayo kusenokubangela ukuba kwenziwe iifreyimu ezikhaphukhaphu nezihlala ixesha elide, nto leyo eyenza kube lula ukunxiba iindondo zamehlo. Ukongezelela, ukusetyenziswa kwe-nanotechnology kubambe amandla okuzilungisa iilensi eziziqhelanisa ngokuzenzekelayo ekutshintsheni iimeko zokukhanyisa, ukubonelela ngombono ofanelekileyo ngamaxesha onke.
Ukuqukumbela, ukuguquka kweeglasi zamehlo kububungqina bokutsha kwabantu kunye nomnqweno wokuphucula amava ethu okubonakalayo. Ukususela kwimvelaphi yazo yamandulo ukuya kwinkqubela phambili yale mihla, iindondo zamehlo ziye zahamba umgama omde. Njengoko itekhnoloji iqhubela phambili, sinokulindela ezinye iimpumelelo eziya kuphucula umbono wethu kwaye ziphucule ubomi bezigidi kwihlabathi liphela.
